Read the text file, parse the data, and add it to objects of your class. You can create your objects either by a constructor or by setters for specific properties.
Which part of this are you having difficulty with?

in the parse the data where I have the problem, I used to read the file:

string[] lines = System.IO.File.ReadAllLines(@"file.txt");
                      
            foreach (string line in lines)
            {
                Console.WriteLine("\t" + line);
            }

Good try, but we are not here to write your programs for you. Take a look at the System.String[^] class and make use of some of its methods to get the results you are looking for. If you really don't know how to get started then try working through this book[^] which contains lots of useful tutorials.

Datagridview moves to first column when selecting row(s)

Hi All,

I have a Form with a Datagridview. The datagridview contains more columns than in the visible area.

Now to my problem:

If I scroll to the right of the datagridview and then select a row or multiple rows the datagridview moves to the left so that the first columns are in the visible area. I would like to keep the columns currently shown to stay in the visible area.

I hope my question is clear and someone can help me.

Thanks
Andre

It is default behavior of datagridview control.
You cannot change it.

There are two tricks to avoid it.

1. You need to minimize the number of columns to display by hiding some of the columns.

DataGridView1.Columns[2].Visible=False;

2. You can change the order of columns so that the columns that require to be visible
for selecting rows comes first so no need to scroll to right side of the grid.

Use the mousedown event and check the eventarguments to see if it's the right button that is clicked.

Both left and right click can be trapped by using the MouseDown event.
Various mouse down events are trapped in the code below.

       private void form1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e) <br />
        {<br />
            // Update the mouse path with the mouse information<br />
            Point mouseDownLocation = new Point(e.X, e.Y);<br />
<br />
            string eventString = null;<br />
            switch (e.Button) {<br />
                case MouseButtons.Left:<br />
                    eventString = "L";<br />
                    break;<br />
                case MouseButtons.Right:<br />
                    eventString = "R";<br />
                    break;<br />
                case MouseButtons.Middle:<br />
                    eventString = "M";<br />
                    break;<br />
                case MouseButtons.XButton1:<br />
                    eventString = "X1";<br />
                    break;<br />
                case MouseButtons.XButton2:<br />
                    eventString = "X2";<br />
                    break;<br />
                case MouseButtons.None:<br />
                default:<br />

Best way to read a file??

Muammar©

25-May-10 22:17

Hi everyone,
Suppose that you have some partly damaged file that you want to copy to somewhere else reading only the good bytes and ignoring the ones that can't be read "getting over them".

I'm using a simple StreamReader in a loop and ignore IOExceptions as they occur but it doesn't work and go very wrong once a cyclic redundancy is encountered..

What would you use?

Re: Best way to read a file??

Richard MacCutchan25-May-10 22:55

Richard MacCutchan

25-May-10 22:55

You should probably use a FileStream[^] as it allows you to read the file at the pure byte level. in this way you are free to interpret the data without any assumptions made by the framework. You can also position your file pointer randomly hence avoiding portions of data that you know are corrupt.
